FEL is an ANSI lamp code for a single-ended 1000W halogen lamp (3200 K, G9.5 base) used in studio and stage lighting fixtures.
Overview
FEL is not a proper noun or an abbreviation, but a three-digit ANSI lamp code. Such codes (e.g., FEL, FKJ, BTL, EHF) uniquely identify a precisely defined lamp across manufacturers based on wattage, base, bulb shape, and voltage. A lamp designated FEL is therefore interchangeable between different manufacturers.
Specifically, FEL designates a single-ended tungsten-halogen lamp (quartz halogen) with 1000 watts and a 2-pin G9.5 base. It belongs to the class of studio/stage/theater lamps (often marked SSTV) and delivers a warm white light typical for tungsten-balanced camera and film technology.
Technical Data
The following values refer to a standard FEL lamp (manufacturer data Osram/Sylvania, 120V version). Exact figures may vary slightly depending on the manufacturer.
| Parameter | Value |
|---|---|
| Lamp Type | Tungsten-Halogen (Quartz Halogen), Single-Ended |
| Wattage | 1000 W |
| Voltage | 120 V (Standard Version) |
| Color Temperature | 3200 K (Tungsten-Balanced) |
| Base | G9.5 (2-Pin) |
| Filament | CC-8 |
| Luminous Flux | approx. 27,000–27,500 lm |
| Average Lifespan | approx. 300 hours |
| Color Rendering (CRI) | close to 100 |
Additionally, related codes exist for different mains voltages; the 230/240V variant in a comparable design is, for example, designated as FEP. Due to the standard voltage of 120V, the classic FEL is primarily common in the North American 120V electrical grid.
Use on Set
The FEL is a classic replacement lamp/light source for tungsten-based studio and stage spotlights with G9.5 sockets, including ERS (Ellipsoidal Reflector Spotlights)/profile spotlights and studio lights. It is used as an interchangeable bulb in fixtures specified for this ANSI code.
With 3200K and very high color rendering, the FEL is designed for artificial light/tungsten-balanced operation and mixes cleanly with other 3200K tungsten equipment. As a halogen lamp, it is dimmable; when dimmed, the color temperature shifts warmer, as with all incandescent lamps. Standard halogen handling rules apply: do not touch with bare fingers (skin oils can burn into the quartz envelope and shorten lifespan), allow to cool down, and observe the permissible burning position.
Special Case: Calibration Lamp
Beyond stage and studio applications, specially burned-in and calibrated FEL lamps are used in laboratories as radiance standards (radiance/irradiance standards), for example, for calibrating photometers, light meters, and spectrometers according to NIST standards. Such certified units are significantly more expensive than standard studio lamps.
